I love adaptive cruise. I have owned this functionality since 2005 with a 2005 XLR and continued with it in my 2009 XLR. So when my wife needed a new car we searched around for various brands that incorporated this technology. With Caddy experience I settled on the 2013 SRX platinum with the tech package and was initially impressed that the adaptive cruise would come to a complete stop (The 2009 XLR adaptive cruise cuts out at 20 mph). However, my enthusiasm quickly faded when I started to notice 2 critical issues:
1. There are many instances where the adaptive cruise control actually forgets that there is a car in front. This does not involve anything like changing lanes -- it is simply a case of following at the normal gap setting (I usually use medium) and then notice that I am approaching the car in front too rapidly even though the dashboard reports that it realizes a car is in front. It is necessary for me to take control with a fairly strong push on the brakes. THIS COULD BE QUITE DANGEROUS. While this does not happen all of the time, it does occur frequently enough that my left foot is positioned very near the brake pedal just in case. This NEVER happens on my XLR.
2. It does not have the "look ahead" range of the XLR. This is especially apparent when entering a highway with the adaptive cruise control set at 65, for example, so it attempts to attain that speed but does not notice until too late that the car in front is actually slowing. My XLR would have picked up that situation way before the SRX does and could have slowed to match the speed of the car in front. The SRX picks up the car too late with too great an approaching speed where the user has to take immediate control. AGAIN, THIS COULD BE VERY DANGEROUS.
I have asked Cadillac service to take a look at the unit to make sure that it is programmed correctly. They only could report that it is programmed correctly to factory specifications. I have specifically asked that the next time a district engineering representative is in the area that he take a drive with me to see firsthand these issues. I wonder if Cadillac is aware of these issues.
